Robust Laser Technology Will Enable Satellite to Measure Greenhouse Gas

BERLIN, July 30, 2020 — The MERLIN satellite, a collaboration between DLR RfM in Germany and CNES in France, will use a radar-like laser system to measure the methane concentration in Earth’s atmosphere. The satellite’s Integrated Path Differential Absorption (IPDA) lidar will send laser light to Earth’s surface and analyze the backscattered signal.
